The screen flickering is a symptom. We need as much info as possible to be able to help you find the root cause. We really have not much to go off of with "screen starts flickering".

Replacing one microcontroller that does it all with atleast 2 other ICs doesnt seem like a good hardware trade-off. The other benefit is the GC controller "just works" and doesnt require experimental software hacks. If you want to try this by all means let us know how it goes.

if the wii looks like your profile pic than I am not convinced its the screen

you are absolutely doing something wrong. What it is, I dont know. You need to do more troubleshooting. I already told you the wiring is not perfect.

It's more likely your wii is not turning on. You need to eliminate a variable by testing the wii on your tv.

if you removed the capacitors like you have done you need to solder on the input side which is the opposite to where you have connected

you've soldered the video in the wrong spot. all your video wires are connected to nothing on the wii. Also the wiring does not look very good.

I dont know. why dont you try it with a video signal

normally it will be blue screen for a few seconds and then turn black.

Do you have an input video signal connected?

Sure it can be made to do that. I hit a wall once I realized the bitbanged implementation couldnt handle receiving more than a few words at a time so it would need a complete overhaul to communicate with a vmu.

RVLoader features GC button remapping now so it sort of does this idea. Full on combos could probably be added as well entirely in software. This is a good approach as it is future proof and doesnt require a hardware change. RVLoader is opensource for anyone who wants to dive in.

Nice job! reminds me of a slimmer version of ashens ps2p

if you have a 3d printer, or someone you know, it can be printed on traditional fdm printer. You will need 22awg multistranded wire and 34 awg magnet wire. Check amazon for this.

aww yeah looking forward to another high quality worklog

Pretty neat device! Never thought I'd see a portable neo geo.

The via soldering here looks very poor. First try to redo the soldering of the GC data via. If same result try the u10 next. This might be a symptom of bad u10 wiring. Hard to say sometimes. Hit it with some flux and reflow and move the wire away from adjacent vias. Check to measure 3.3v on...

The 4layer boards are not designed for this. I think the best purpose of these files is if you already have a GBoy kit and want to upgrade your case. I am working on a new gboy version with the new boards so hang tight.
